# OMB Briefing April 6, 2011

# What are we proposing for 

# major sources?  

# We are proposing MACT standards for new and existing PVC production facilities at major sources  

# In 2004 the major source MACT was vacated  

# Court said EPA failed to show that regulating VC satisfied requirements to regulate all HAP 

#  

# Now under settlement agreement with LEAN, MEAN and Sierra Club requiring Administrator’s signature on the proposal by April 15, 2011

# What are we proposing for area sources?  

# On January 23, 2007, EPA promulgated standards for area sources  

# Established GACT standards for VC equivalent to part 61 

# VC NESHAP, which covers process vents, stripped resins, wastewater and equipment leaks 

#  

# We are proposing to review and revise those standards  

# Vinyl chloride standards under CAA 112(d)(6)  

# Total HAP standards under CAA 112(d)(5)  

# Dioxin and HCl standards under CAA 112(d)(2)  

# Include standards for heat exchange systems and storage vessels

# Why are we addressing area source 

# standards in this rulemaking proposal?  

# Area sources should be regulated commensurate with major sources given unique circumstances surrounding this category  

# The area source is located in the community that sued us  

# Litigants filed a Petition against the United States for violating their right to equal environmental protection, 

# citing effects from industrial facilities in Mossville, LA and EPA’s failure to set MACT standards  

# CNN's Toxic's Town Series featured Mossville residents and their exposure to chemicals from chemical plants including the CertainTeed Corporation area source

# Why are we proposing area source standards equivalent to MACT levels for major sources?

 

# At the time of the 2007 area source promulgation, we were unaware that there were any area sources  

# Only area source is CertainTeed Corporation in Mossville, LA  

# It is a “synthetic” area source and would emit at major source levels except for thermal oxidizer required by Louisiana  

# 114 survey information we collected shows no substantial 

# differences between this source and other major sources, with the exception of their stripped resin  

## Area and major sources have similar emissions  

## Area and major sources use the same types of control devices

# What are we proposing to do?  

## Set standards for all PVC area and major sources:  

## Process vents (recovery system and activate carbon injection/fabric filter)  

## PVC stripped resin (steam stripping)  

## Equipment leaks (LDAR)  

## Wastewater (steam stripping)  

## Heat exchange systems (equipment leak program)  

## Storage vessels 

##  

## Set emission limits for:  

## Vinyl chloride  

## Total HAP  

## Dioxin & furans (as TEQ)  

## Hydrogen chloride (HCl) 

##  

## Set monitoring requirements:  

## Annual source testing  

## Parametric monitoring
